A relationship you build which is only useful for a short period of time. Perhaps with a client, a fling, the guynext to you on an airplane or bus, a fellow sports fan at a bar or any other form of good human contact which will end after a short period of time.
We became best friends in about 5 minutes, but it was just a throw awaytionship and i'll neversee them again
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
